I or 'IBUFFALO, NEW YORK LOOSE-LEAF BINDER Application filed March 13,1929. Serial No. 346,593.

The invention relates to temporary binders and it has particularrelation to binders of the'loosleaftype in which the cover membersmaybejadjusted towa'rd andaway from --0ne'-*anor11er ini'order to clampgroups of 7 pages of varying members therebetween or to p'rmi'tofthe-quick'removal of the pages therefrom or the insertion of additional*both releasing the covers from 'clampedposition'and'jfor movingthem'relative to each other in order to permit of the quick and" easy'insertion or removal of pages from'the binder. i

Another object of the invention is to provideianovel locking mechanismfor a binder ofthe character described which is simple in constructionand' arrangement andwhich' maybe assembled and disassembledwith aminimum of time andeffort'.

Other objects of the invention will appear from the" followingspecification and append edcl'ain1's;" 1 I} r s I V In the accompanyingdrawing, Fig. 1 is a plan view of a loose leaf binder with the coversthereof in 1 an open position andiwith portions broken away I to moreclearly illustrate the improved adjusting and locking mechanism.

Fig.2 is an enlarged sectional view of a portion of the binder'taken online of Fig. 1. s p j I Fig. 3 is an enlarged fragmentary plan viewofthe improved locking mechanism.

Fig. 4 is 'atransverse' sectional view taken on line4 l of Fig. 3.

Referring to the drawing, abinder con structed 1n accordance with thepresent invention is shown as comprising a pair of cover members 1 and 2each of which includes a rectangular frame 3 having sheet metal platesetand 5 secured to the innerand outer sides thereof by rivets 6. Channelmembers cover members land '2 respectivelyand are formed with earportions 8, 2), which are pivotally connected to ears 9 provided on eachof a pair of clamping bars 10. Thse bars are providedwith apertures 11adapted to receive the ends of a pair of studs 12 which are carried by apair of transfer bars 13. The transfer bars 13 directly engage theopposite sides of a group of pages 14 and are each provided with a pairof posts 12 which extend in opposite directions through a series ofregistering perforations 15 formed in the pages.

An adjusting bar 17 extends across the cover 1 between the plates 4 and5 and is provided with a plate member 18 formed with a central offsetportion 18' toprovide a guideway for slidably receiving a ratchet bar 19which is secured to the cover 1 between the plates 4 and 5. The oppositeends of this plate member 18 are suitably secured to the bar 17. Apairof flexible straps or thongs 20' are each secured at one end to theadjusting bar 17 by a clip 21 (Fig. 1), and extend through the channelmembers 8 and through slots 22 provided in the transfer bars 13 and arefixed at their other ends in the channel members 8 carried by the covermember 2. The stack or group of pages 14 is preferably notchedtransversely as indicated at 23, (Fig. 2), in order to receive thethongs 20 where they cross from cover to cover back of the pages.

The adjusted bar 17 is locked in adjusting bars 10 together by means ofa pawl 24 which is pivotally mounted as at 25 upon the bar 17 and whichis yieldably urged into engagement with the rack bar 19 by means of aspring 26. A plate 27 is fixed to the pawl 24 by means of a rivet or thelike 27 and is formed with a projection or finger 28 which projects intoa slot or recess 29 formed in the offset portion 18' of plate member 18,and overlies the rack bar 19 for engagement by a pin 30. This slot 29 inplate 18 extends through one end of the plate as indicated at 29 toaccommodate the'pawl 24:. This pin extends transversely through a stud0r rotatable member 31 which is rotatably mounted in the bar 17 andextends through an Opening in plate 18 and is provided with an annularshoulder or collar 32, (Fig. 4), to prevent the upward displacementthereof. The stud 31 is slotted as at 33 to receive a handle 34 which ispivotally mounted on the pin and which extends throughaslot 35,- (Fig.1), formed in the plate 4 of the cover. The handle 34 is provided with ashoulder 86 for engagement with the stud to arrest the upward or outwardswingingniovement of th han dle 34 in a position substantiallyperpendicular to the plane of the cover. A leaf spring 37 bears againstthe lower extremities of the handle '34" and tends to normallymaintain't-he handle in an inoperative position flat against the cover.

lVhen it is desired to release the covers to permit of the insertion ofpages in the hind er or'the removalof pages therefrom, the handle 34 isfirst swung upwardly about the pin 30 against the action of the spring86 to the position shown in Fig.4. The handle is then turned about anaxis substantially normal to I the plane of the'cover thus causing thepin30 The to bear against the finger 28. of the plate 27 and release theratchet 24 from engagement withthe rack 19 against the action of thespring 26. As soon as the ratchet is released onthe'handle in tighteningthe adjusting bar and thongs in an adjusted position.

From the foregoing it will be apparent that'a very simple and efficientmechanism is provided and in which the parts may be quickly assembledand disassembled. For

example, the pin 30 performs the triple funo- I 'tionof serving as alever to operate the pawl, maintaining the stud 31 against displacementfrom the plane'of thebar 17 and providing a' pivotal bearing forthehandle 34, thus permittingof-rquickrassembly or disassembly of parts: Y
